Atypical squamous cell of undetermined significance (ASCUS) is a common cervical cytological diagnosis. At present, HPV DNA assay is used to triage these patients, but its lower specificity brings a series of problems. The purpose of this study was to evaluated the value of p16/Ki67 immunostaining, HPV E6/E7 mRNA testing in triaging women with ASCUS by comparing HPV DNA assay.
Liquid based cytology specimens were collected from 300 patients. P16/Ki67 immunocytochemistry using the CINtec® Plus Kit and HPV E6/E7 mRNA testing by QuantiVirus®HPV E6/E7 mRNA assay used the same cytology sample. Detection rates of each test were evaluated against histopathology.
All assays yielded a high sensitivity for the detection of CIN3+ (100% (86.7-100) for HPV DNA assay, 88.0% (70.0-95.8) for HPV E6/E7 mRNA testing and 100% (86.7-100) for p16/Ki67 immunocytochemistry) and CIN2+ (98.2% (90.2-99.7) for HPV DNA assay, 87.0% (75.6-93.6) for HPV E6/E7 mRNA testing, 98.2% (90.2-99.7) for p16/Ki67 immunocytochemistry). The specificity to detect high grade dysplasia was highest for p16/Ki67 immunocytochemistry (74.2% (68.7-79.0) in CIN3+ and 82.5% (77.3-86.8) in CIN2+), followed by HPV E6/E7 mRNA testing (39.6% (34.0-45.5) in CIN3+ and 42.7% (36.7-48.9) in CIN2+) and HPV DNA assay (16.0% (12.1-20.8) in CIN3+ and 17.5% (13.2-22.7) in CIN2+).
p16/Ki67 immunostaining and HPV E6/E7 mRNA testing, especially the former, may be promising tools in triage of ASCUS.
非典型鳞状细胞意义不明确（ASCUS）是常见的宫颈细胞学诊断。目前，HPV DNA 检测用于对这些患者进行分流，但它的特异性较低带来了一系列问题。本研究旨在通过比较 HPV DNA 检测评估 p16/Ki67 免疫染色、HPV E6/E7 mRNA 检测在 ASCUS 患者分流中的价值。
收集 300 例患者的液基细胞学标本。使用 CINtec®Plus 试剂盒进行 p16/Ki67 免疫细胞化学染色，使用 QuantiVirus®HPV E6/E7 mRNA 检测试剂盒进行 HPV E6/E7 mRNA 检测，使用相同的细胞学样本。根据组织病理学评估每种检测方法的检测率。
所有检测方法对 CIN3+的检测均具有较高的敏感性（HPV DNA 检测 100%（86.7-100），HPV E6/E7 mRNA 检测 88.0%（70.0-95.8），p16/Ki67 免疫细胞化学染色 100%（86.7-100））和 CIN2+（HPV DNA 检测 98.2%（90.2-99.7），HPV E6/E7 mRNA 检测 87.0%（75.6-93.6），p16/Ki67 免疫细胞化学染色 98.2%（90.2-99.7））。检测高级别发育不良的特异性以 p16/Ki67 免疫细胞化学染色最高（CIN3+为 74.2%（68.7-79.0），CIN2+为 82.5%（77.3-86.8）），其次是 HPV E6/E7 mRNA 检测（CIN3+为 39.6%（34.0-45.5），CIN2+为 42.7%（36.7-48.9））和 HPV DNA 检测（CIN3+为 16.0%（12.1-20.8），CIN2+为 17.5%（13.2-22.7））。
p16/Ki67 免疫染色和 HPV E6/E7 mRNA 检测，尤其是前者，可能是 ASCUS 患者分流的有前途的工具。
